Power over Ethernet (PoE) Industry Applications

Key Sectors: Security & Surveillance, Smart Home, Industrial Automation, Digital Signage, IoT, and More

---

1. Security & Surveillance

Applications:

• IP Cameras: PoE simplifies cabling for high-resolution (4K) surveillance.

• Access Control: PoE-powered door controllers, card readers, and facial recognition terminals.

• Alarm Systems: PoE smoke detectors, motion sensors, and emergency buttons.

• NVR Systems: PoE switches connect multiple cameras without extra power adapters.

Advantages:
✔ Single-cable solution (power + data) reduces installation costs
✔ Remote power management (e.g., device reboot)
✔ High reliability for outdoor/weatherproof designs
